Tom Terrific was an early animated series on American television, presented as part of the Captain Kangaroo children's television show. Created by Gene Deitch under the Terrytoons studio (which was a subsidiary of CBS), Tom Terrific ran in a series of five-minute cartoons created specifically for the Captain Kangaroo show from 1957-1959, and was rerun on Kangaroo for years thereafter. Drawn in a simple, even clumsy, style, it featured a gee-whiz boy hero, Tom Terrific, who lived in a treehouse and could transform himself into anything he wanted thanks to his magic "thinking cap" funnel hat, which also enhanced his intelligence. He had a comic lazybones of a sidekick, Mighty Manfred the Wonder Dog, and an arch-foe named Crabby Appleton, whose motto was "Rotten to the core!" Other foes included Mr. Instant, the Instant Thing King; Captain Kidney Bean; Sweet Tooth Sam, the Candy Bandit; and Isotope Feaney. There were 26 stories produced, the first thirteen filmed in 1957; the remaining thirteen filmed in 1958. Each story was split into five parts for broadcast each weekday morning. There has never been an authorisized VHS or DVD release of the series, so it's pretty rare material.
